How the numbers are built

The site is a live model, not direct observation. Every counter combines a population or event baseline with geographic distribution, local time, participation, typical duration and an activity-specific hourly curve.

Core model

baseline estimate = Σ (country population × age/eligible share × bounded probability at civil local time)

A region at 03:00 contributes much more to sleeping than one at 15:00. Work, meals, commuting, exercise and evening leisure each use a different deterministic curve. Activity curves are deterministic; only the explicitly labelled birth/death current-second illustration uses seeded Poisson sampling.

Measured inputs, explicit simulation

All 102 counters remain available. A counter is not made scientific merely by linking to an institution. The input's year, unit, population universe and conversion must also match. We distinguish a measured or published anchor from the assumptions required to show a current moment.

What “237 countries” actually covers

The model includes 237 non-overlapping countries or areas. Their 2026 mid-year populations sum to within two people of the original UN world total, a source-rounding difference. 2024 age shares match 216 records; Internet-use shares match 182. Missing shares use the world mean as a labelled proxy, never zero.

IANA civil zones are matched for 236 records. Existing documented multi-zone weights are reused where available; some other countries use a representative zone and one unmatched area contributes a flat residual. CLDR weekend conventions identify civil weekends, not proof that everyone stops working. Borrowed US weekday/weekend behaviour remains a geographic proxy. Each eligible group's activity probability is bounded to 0–100%; daily curves are recalibrated after bounding so their daily person-time is preserved.

Population coverage is not behavioural measurement coverage. We do not claim that all activities are measured across 70–80% of humanity, nor that these are independently validated simultaneous headcounts. Sensitivity ranges are editorial scenarios, not confidence intervals. Birth/death per-second integers are reproducible Poisson simulations, not observed events.

Deeper country layer

How the global Working estimate is built

India, China, the United States, Indonesia, Pakistan, Nigeria, Brazil, Bangladesh, Russia, Ethiopia, Mexico, Japan, Egypt, the Philippines and DR Congo are calculated separately, and EU-27 is added as a non-overlapping official-data region. Its population labels now use the same current UN interpolation as the rest of the site; labour-input vintages and holiday-effect assumptions remain separately documented.

global working = Σ (15 country models + EU-27) + population-weighted rest-of-world model

Each tracked region uses DST-aware IANA time zones, its own labour or time-use anchor and country-specific weekly schedules. Verified 2026 calendars are used where available. Bangladesh and Egypt use Friday–Saturday weekends; China’s official makeup workdays override its ordinary weekend rule. DR Congo remains explicitly Experimental because a complete official 2026 holiday calendar was not verified.

Country anchors

What is measured and what is modelled? Population, employment/time-use anchors, workweek provisions and calendar dates come from the linked sources. Smooth start/end-of-day curves and reduction factors for closures are documented modelling bridges because no government publishes a second-by-second national worker count.

Holiday coverage is intentionally conservative. Federal or central-government holidays do not mean every private business closes; regional holidays and industry-specific shifts can differ. EU-27 common-date coverage is rounded into broad population shares, so national-only and regional holidays are not yet all applied. Pakistan’s Islamic dates remain subject to official moon-sighting changes. Calendars are updated by year.

Other reference baselines

Editorial assumptions

There is no worldwide, second-by-second database for most human activities. Eligibility, participation, frequency and duration are rounded assumptions unless an activity names a more specific source. Source links and modelling bridges are kept separate.

One person can appear in several estimates at once. Someone may be working, online, listening to music and drinking coffee, so activity totals are not mutually exclusive.

Country and region mode

The dedicated United States experience uses its own ten-activity ATUS model. In “Around You”, EU-27 is also selectable as one region: ordinary counters sum the 27 member countries with their DST-aware civil clocks, while Working additionally uses the Eurostat labour/weekend/calendar layer above.

Trends and 24-hour charts

“Rising Right Now” compares the current model output with the same model 30 minutes earlier. A 24-hour chart is a typical modelled curve, not observed history.

Limitations

Country schedules cannot capture every occupation, night shift, informal job, religious observance, regional calendar, labour-force transition or exceptional closure. The Working counter is more correlated with documented country conditions than the previous generic model, but it remains an estimate rather than surveillance or a labour-force census.
